omxCheckWithinPercentError: Approximate Percent Equality Testing Function

Description

This function tests whether two numeric vectors or matrixes are approximately equal to one another, within a specified percentage.

Usage

omxCheckWithinPercentError(a, b, percent = 0.1)

Arguments

a

a numeric vector or matrix.

b

a numeric vector or matrix.

percent

a non-negative percentage.

Details

Arguments a and b must be of the same type, ie. they must be either vectors of equal dimension or matrices of equal dimension. The two arguments are compared element-wise for approximate equality. If the absolute value of the difference of any two values is greater than the percentage difference of a, then an error will be thrown. If a and b are approximately equal to each other, by default the function will print a statement informing the user the test has passed. To turn off these print statements use options("mxPrintUnitTests" = FALSE).

# Throws an error
try(omxCheckWithinPercentError(c(1, 2, 3), c(1.1, 1.9 ,3.0), percent = 0.01))
